Best Coaxial Cable for Internet Reviews

1. Mediabridge Coaxial Cable

The Mediabridge Coaxial Cable is an excellent choice when you need to connect your modem to an external source that is a bit distant from your home.

The triple-shielding used by the makers makes this usable for both indoor and outdoor applications. Its construction is solid and robust to endure changing conditions without quality compromise.

Notably, the end connectors themselves are nickel-plated, improving their durability and increasing transmission efficiency from the port to the line.

Furthermore, it’s UL-rated, so you could safely install the cable inside your walls. Once you have finished the install and found that you have some extra length, the included adjustable and reusable Velcro straps can help you manage the cables and keep them clean.

Installing the high quality coax cable is also so much easier with the EZ Grip Connector caps that come free with the package. Hence, you do not have to purchase extra tools beforehand to set up this cable system.

The only downside that I experienced with this product is that it’s quite a stiff cable. Uncoiling and installing it was quite a challenge.

However, it is not an issue for me since I would do the installation one-time only, and the increased stiffness means a much more enduring and stable connection.

What to Look for When Buying Coaxial Cable for Internet


When choosing the best coaxial cable for your use, it is important to consider several factors that ensure smooth transmission and stable signal. Ease in installation, whether you want the cable across the room or inside the wall, is also vital.

The first thing you should find is the length you need. Although you could presumably purchase the longest cable you think you need, cable management can be quite tricky. Hence, I always recommend that you get the wire that would suffice for the distance from the receptacle to the modem – with only a foot extra or so.

Next, determine if you’re going to place the coax. Is it going to be run outside the house to the telephone company? Or are you going to use it to connect your modem to the wall receptacle? Or maybe you’re planning to use it for installation under the wall? Knowing where it will go is essential as you must have a properly-rated wire for each specific application.

Furthermore, do not forget to check out the connectors. It is advisable to opt for well-built pieces that will not disconnect from the cable as time goes on. It’s going to be a major hassle for you if your in-wall coax cable suddenly separates from the modem. You can make sure that it won’t break by checking the boot’s quality and giving it a good tug to see if it will move a bit or not.

What Type of Coaxial Cable is Best for the Internet


The best coaxial cables to use for internet connections should be the thicker ones. I prefer those with better shielding, thicker installation, and a solid core so that I can have excellent and efficient signal transfer while preventing interference from outside sources.

Does It Matter What Coaxial Cable I Use for the Internet

Yes. A poor quality coaxial cable can cause errors – and even let you have a bad connection. You won’t be able to maximize the high-speed internet you’ve subscribed to if your coaxial cable is not up to the task. I also recommend that you get wires rated for 3 GHz as internet companies are slowly migrating towards that standard.

Does Coaxial Cable Affect Internet Speed

Not necessarily. What happens is that cable core imperfections, interference due to inadequate shielding, or loose connectors cause errors, negatively affecting your signal quality – causing web pages not to load and make you seem to have “slow” internet.

Its ability to connect us through the Internet is an indispensable capability. Because of this, we have put together a list of top-rated cat 7 ethernet cables and cat 8 ethernet cables. Read it for more information.

How Far Can You Run an RG6 Cable for the Internet

For your information, an RG6 cable for the internet can run up to 1000 feet. But for such a length, you would need to install two switches for both ends to ensure a stable signal.


The best coaxial cable for internet would always depend on your current needs. No one wire has the monopoly on being the best one to use for the internet. By determining the length, the installation type, and even the color that you need, you could get the best one for your use.

However, out of all the brands in the market, the twelve products reviewed above are those I’ve worked with before and haven’t had any problems with. I’m sure you could find them online or at your nearby hardware store.
